Background
In the atomization device, the core element is the heating element, the core technology is the temperature control of the heating element, and the key for carrying out the temperature control is to measure the temperature of the heating element. The heating element is usually a heating element resistor, and generates heat by supplying power to the heating element resistor, thereby heating the atomized substrate to raise the temperature of the atomized substrate and generate the aerosol or aerosol. In the current heating circuit, a sampling resistor is connected in series on a heating loop to detect the resistance of a heating element resistor, then the voltage drop on the sampling resistor is amplified by an operational amplifier and then is collected and calculated by an MCU (microprogrammed control unit), and the MCU obtains current through I ═ U/R. Because the MCU voltage is usually obtained after being stepped down by the LDO, the voltage that the MCU can collect is smaller than the voltage of the heating power supply (battery), so the voltage on the heating element resistor needs to be collected by the MCU after being divided by the sampling resistor, and then the resistance of the heating element resistor is calculated by R ═ U/I. In this way, since the sampling resistor is connected in series to the heating circuit, the sampling resistance value needs to be very small (in the order of m Ω) so as not to affect the heating efficiency, and the voltage drop of the sampling resistor needs to be amplified by adding the operational amplifier because the voltage drop of the sampling resistor is very small. Because the sampling resistance is very little, the precision of resistance itself is difficult to accomplish very high, in addition there is the error of operational amplifier itself, and the current error of sampling just is bigger like this, and in addition the precision error of sampling resistance makes the voltage on the heat-generating body resistance of gathering also have the error, thereby the resistance error of heat-generating body resistance that calculates through R ═ U/I is just bigger, owing to need increase operational amplifier, the cost is higher moreover.
